One of the main reasons that led to online casinos becoming so popular was the sheer choice of games that they offer. Hundreds of online slots have been released over the years, with some being more popular than others. We went through a large selection of games by some of the most renowned providers such as NetEnt, Microgaming and Playtech, as well as some of the smaller slots developers and we’ve selected five top-notch online slots. Here are our picks.

Starburst

NetEnt’s Starburst was released in 2012 at the beginning of the year and we have to say that it is still played regularly today. In fact, there are several casinos that are still offering free spins bonuses on Starburst, which in itself is a testament to the game’s popularity.

Starburst features a standard layout with five reels and three rows, and there are ten paylines which can be activated with a minimum of 1p per line, or a total minimum of 10p. The maximum amount that you can wager per spin on Starburst is £100. The game’s RTP is set at 96.10%.

Centurion

Roman-themed slots and slot games with a historic theme in general are immensely popular, but of course not all games are made the same. Centurion slots by Inspired is not just one of the most popular history slots, it is one of the most played games in general.

Released in 2015, this five-reel game with 20 paylines can be played with a minimum stake of 20p, whereas the maximum wager is set at £250. When it comes to symbols, you will immediately realise that it’s a Roman-themed game as there are coins, swords, helmets and centurions on the reels. The maximum in-game prize is 500x your coin size.

Fishin’ Frenzy

Fishing is a favourite pastime of many, especially in regions where there are rivers, lakes, and of course, places on the sea. Fishin’ Frenzy is a game by Reel Time Gaming, a provider that might not be as renowned as Microgaming or NetEnt, but one that has definitely developed a range of popular games over the years.

Fishin’ Frenzy was also launched in 2015, so it seems that this year was quite prolific for slots developers. The Fishin’ Frenzy RTP is 96.12% and the game features ten paylines. The maximum wager is £40.

Double Bubble

This game was produced by Gamesys, another smaller developer which has, nonetheless, developed quite a few exciting online slots. Double Bubble is singled out because of the unique gameplay and its quirkiness, despite the fact that it resembles older retro slots.

The game comes with a standard layout – five reel and three rows, with a total of 20 paylines. Double Bubble slot was released in 2014 and even though it’s been quite a while since the initial release, it is still one of the most played online slots.

The game’s RTP may vary between 95.75% and 96.24% which makes Double Bubble one of the few games where this is flexible.

Thunderstruck II

You can’t have a list of top games without a Microgaming slot. Thunderstruck II, released in 2010, is the sequel to the original Thunderstruck from 2004. Norse mythology is the theme and the game comes with five reels and a total of 243 ways to win.

The main Thunderstruck II bonus feature is called The Great Hall of Spins and it includes four mini bonuses and one which is triggered depends on how many times you’ve managed to activate the bonus. The RTP is set at 96.65%, higher than the return that you would get on most other online slots.
